The Stanley Fibreglass Claw Hammer has a reinforced fibreglass shaft, fitted with a rubberised contoured grip. The combination of the two results in increased shock absorption and hence a hammer that is far more comfortable to use with far less hand fatigue. The hammer holder has a belt loop for fitting to your work belt. It keeps your hammer out of the way when not in use and immediately to hand when needed. Hammer weight 450g (16oz).
